Figure 5.11. Comparison of exact deflection solution and Abaqus solution for an aluminum
beam meshed with 8 elements and subjected to a dynamic load.
From Figure 5.9, Figure 5.10 and Figure 5.11, we observe that Abaqus results for a
beam meshed with 8 elements through the thickness produced the best match with theoretical
results. A minimum of 8 elements through the thickness would thus be used for all further
modeling work.
5.3 Crack modeling benchmark tests
A 254 mm × 25.4 mm IM7/SC780 composite coupon was modeled using three
dimensional eight node linear brick elements (C3D8R). The stacking sequence for the
composite coupon was [016]T. The damaged composite coupon was modeled with a crack in
the middle four plies extending through the width. The material properties used in this model
are listed in Table 5.7 and were determined by performing experimental material
characterization tests.
